M AC HI NE FOR CUTTING WOOD EN BOX-BLANKS.

SPECIFICATION forming part of Letters Patent No. 224,437, dated February 10, 1880.

- Application filed November 13, 1879.

To all whom it may concern:

Be it known that I, WILLIAM HUEY, of Cambridge, in the county of Dorchesterand State of Maryland, have invented a new and Improved Machine for Cutting Blanks for Wooden Boxes; and Ido hereby declarethat the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming part of this specification, in which- Figure l is a side elevation. Fig. 2 is a vertical longitudinal section through the line as a: of Fig. 3. Fig. 3 is a plan view 5 Fig. 4, an enlarged detail plan View of the cutterplate; Fig. 5, an edge view of the same, with the clamping-strip for holding the cutter removed. Fig. '6 represents details of the several forms of cutters. 7

My invention relates to a machine for cutting blanks from a block of wood and simultaneously grooving the said blank preparatory to bending it into form rectangular sides of a box. 7

The invention consists in the peculiar construction and arrangement of a stationary horizontal knife "bolted stron' gly to a bed-frame, so that it cannot bendwhen under strain; an

adjustable gage-plate with groove-cutters ar-' ranged just in front of the knife and just enough below its edge to give the proper thickness of blank, together with a reciprocating block-carrier.

The invention also consists in the arrangement and adjustment of cutters on a plate is arranged the knife B, Figs. 2 and 3, which is arranged with its edge inward, and is bolted strongly down to its solid bed-frame, so that,

r it will not be liable to bend under a strain and spoil the blank-objections which applyto all for making the reciprocating knives, for the reason that if they r are made heavy enough to resist this istrain they are too heavy to be practical. Just {in front of the edge of the knife is arranged the cutter-plate G, which is bolted to the framework (see Fig. 1) through a slot, 01, in the gage- ;plate D, which latter is adjusted vertically to regulate the distance between the cutter-plate and the knife, so as to give the required thickgne'ss to the blank by means of inclines a and adjusting-screw b. For permitting, this ad justment the bolt or screw 0 in plate 0 is loosened, and the plate D is then moved horizontally by its set-screw b, the movement ofthe plate D under 0 being permitted by the slot d. Upon the surface of the cutter-plate an d near the edge of the knife are arranged the cutters 10 a e e and f f, of which 0 e serve to cut the transverse grooves which determine the position of the corners and facilitate the bend- I form the lap-joint described and claimed in my application for an' egg carrier and crate "filed the same date herewith. For making this joint one of the cutters e of the machine is connected with the incline cutter f, or it may simply be arranged adjacent thereto. For making the grooves at any desired position in the length of the blank to give the box any desired proportion between the sides and ends, the edge of the cutterplate 0 next the knife is rabbeted or recessed, and the cutters are fixed adjustably in said recess, and are clamped-in any desired position by the vmetal strip E, (see Fig. 4,) which is drawn against the same by screws 9. Over the cutter plate and knife there reciprocates the block-carrier F, which latter is formed at its horizontal ends with grooved slides h h, that move over guides t 0', formed in the shape of tongues on the tops of vertically-adjustable plates G G upon opposite sides of the machine. The block-carrier is reciprocated by pitmen jj, connected by crank-pins with a drive-shaft carrying a heavy drive-pulley, H, which shaft and pulley are located in bearings upon the narrow elongated portion A of the frame as far away as possible from the cutting device. This distant location of the drive-shaft not only enables the pitmen to work to good advantage of leverage, but it leaves a good table or support at 0, Fig. l, to hold the heavy metal gage-plate or cutter-plate in adjusting, sharpening, or repairing the same. The block-carrier is formed with a vertical face, 11, against which the block is held by the bar g, which is adjusted by bolts in the end pieces or guides to suit the width of the block, and also by arms M", Fig. 3, which are also adjusted by bolts in the bar q against the ends of the block to prevent it from moving lengthwise. The block being thus held against horizontal displacement, it is fed down as fast as it is sliced off by the heavy metal follower I, which is provided with griping-teeth on its lower surface, and rests with its full weight upon the block. (Shown at m, Fig. 2.) This heavy follower, it will be seen, makes an automatic feed for the block. In inserting a new block it is necessary to elevate the follower and hold it in this elevated position until the block is inserted. For this purpose the faceplate p of the carrier is slotted vertically, and through these slots the follower is attached to ahorizontal bar provided with vertical racks w, with which mesh the piuions y on the horizontal shaft t, by rotating which shaft the follower may be conveniently raised, the shaft and follower being held to this adjustment while the block is being inserted by means of a ratchet-wheel, u, on said shaft and a pawl or detent, 1;. (See Fig. 1.)

I do not claim, broadly, a weighted follower for holding the block to its place, as these have been used in holding blocks for cutting veneers, 850. My construction of weighted follower, however, made of equal length with the block-carrier, and having arms projecting through vertical guide-slots in the face of the block-carrier, constitutes a meritorious construction well adapted to my purpose.

In order to secure a clean and sharp cut for the blank it is necessary that the lower edge of the face 19 should have a sharp and well-defined edge, and for this reason there is secured to said edge a metal plate, 2, Fig. 2, which plate is made of some soft metal, like brass or Babbitt metal, to avoid any injury to the knife edge in case it comes in contact with the same. As fast as this edge wears away it is adjusted lower down by lowering the end plate, G G, carrying the guides, by means of the bolts 1) and slots 11 Having thus described my invention, what I claim as new isl. The gage-plate D, made adjustable by inclines and screw, as described, in combination with the adjustable cutter-plate 0 above, provided with the groove and incline cutters, and the stationary knife, as set forth.

2. The cutter-plate having a recess or rabbet in its edge next to the knife, in combination with a set of detachable and adjustable cutters, and a clamping-strip, E, secured to plate 0, as described, and between which and the shoulder in O the cutters are held, as de scribed.

3. The reciprocating block'carrier F, having a vertical face, 19, with vertical guide-slots therein, in combination with the weighted fol-. lower 1, made of equal length with the blockcarrier, and having extensions projecting through the slots in the face 12, as described.

4. The combination, with the stationary cutters, of the reciprocating block-carrier and the guide-plates G G for holding the same, made vertically adjustable by means of slots and set-screws, as and for the purpose described.
